Refusing bottle

Anyone else’s baby refusing the bottle? My daughter won’t take her usual 28oz of formula a day. She won’t drink from a sippy either. I’ve tried juice/water/milk...nothing works. She will maybe drink 14-21 oz a day but it’s a struggle. She eats fine. I’m worried about dehydration. I’m monitoring her urine output and watching for tears when she cries. Anyone dealing with anything similar?
